---|---|---|
1 | USB HOST USB B 2.0 Connector | Connect to the USB host (for example, a |
laptop) to communicate with the USB
peripheral devices (for example, a smart board) connected to USB device ports
on either the transmitter or the receiver sides of the extender (see Step
4:Connect inputs and outputs).
2| ACTIVE HOST LED| Lights orange when the USB host side is active
3| ACTIVE Rx LED| Lights green when the extender receiver function is active
4| IN LED| Lights blue when an active HDMI input signal is detected on HDMI
IN.
5| OUT LED| Lights blue when an output acceptor device is connected.
6| TX LOOP| Transmitter mode| Lights blue an active signal is transmitted on
the Tx LOOP port.
Receiver mode| N/A
7| LINK LED| Lights green when the HDBT active link connection is established.
8| ON LED| Lights green when the device receives power.
9| HDBT RJ-45 Connector| Connect to the HDBT RJ-45 connector on a paired
receiver/transmitter device (for example, a second EXT3-TR device).
10| HDMI TX IN Connector| Transmitter mode| Connect to an HDMI source.
Receiver Mode| N/A
11| HDMI Rx OUT/Tx LOOP Connector| Transmitter mode| Connect to a local
acceptor.
Receiver mode| Connect to an HDMI acceptor.
12| USB A 2.0 Connector 1| Connect to the USB local peripheral devices (for

and charging power for this port are inactive.
13| USB A 2.0 Connectors 2-3| Connect to the USB local peripheral devices (for
example, a USB camera, a soundbar, microphone and so on). When USB Host PC is
disconnected, the USB charging power for this port continues to be active.
14| IR 3.5mm Mini Jack Connector| Connect to an external IR emitter to control
a local IR-controlled device from the remote extender (for example, EXT3-TR).
Connect to an IR sensor to control a remote IR-controlled device connected to
the remote extender side (for example, EXT3-TR).
15| RS-232 3-pin Terminal Block| Connect to a controller device (for example,
SL-240C) to control a remote device via serial connection (for example, the
remotely connected PTZ USB camera).
16| ETHERNET RJ-45 Connector| Connect to LAN.
17| SETUP 4-way DIP-switch| Sets the device behavior (see Step 4:Connect

Mount EXT3-TR
Install EXT3-TR using one of the following methods:
-
Attach the rubber feet and place the unit on a flat surface.
-
Fasten a bracket (included) on each side of the unit and attach it to a flat surface (see www.kramerav.com/downloads/EXT3-TR).
-
Mount the unit in a rack using the recommended rack adapter (see www.kramerav.com/product/EXT3-TR).
-
Ensure that the environment (e.g., maximum ambient temperature & air flow) is compatible for the device.
-
Avoid uneven mechanical loading.
-
Appropriate consideration of equipment nameplate ratings should be used for avoiding overloading of the circuits.
-
Reliable earthing of rack-mounted equipment should be maintained.
-
Maximum mounting height for the device is 2 meters.
Connect inputs and outputs
Always switch OFF the power on each device before connecting it to your EXT3-TR extender.
Wiring the RJ-45 Connectors
This section defines the HDBT pinout, using a straight pin-to-pin cable with
RJ-45 connectors.
For HDBT cables, it is recommended that the cable ground shielding be
connected/soldered to the connector shield.
To achieve specified extension distances, use the recommended Kramer cables
available at
www.kramerav.com/product/EXT3-TR.
Using third-party cables may cause damage!
